Graham to Obama: 'Not your strong suit'

Sen. Lindsey Graham said on Sunday that President Barack Obama needs to "stop going on television and trying to threaten thugs and dictators."

"It is not your strong suit. Every time the president goes on national television and threatens [Russian leader Vladimir] Putin or anyone like Putin, everyone’s eyes roll, including mine," the South Carolina Republican said on CNN's "State of the Union."

Addressing the conflict between Ukraine and Russia, Graham said the United States has a "weak and indecisive president that invited aggression."

"President Obama needs to do something," Graham said. "How about this: Suspend Russian membership in the G-8 and the G-20 at least for a year, starting right now and every day they stay in Crimea after the suspension. Do something.”
